Description

Vorrichtung zur Glättung der Oberfläche von gewalzten Stangen oder Drähten Die Erfindung betrifft eine Einrichtung zurr Glättung und Säuberung der Oberfläche von Drähten und gewalzten Stangen zwecks Beseitigung der bei den vorhergehenden Arb;eitsgängen entstandenen Verunreinigungen.Device for smoothing the surface of rolled bars or Wires The invention relates to a device for smoothing and cleaning the Surface of wires and rolled bars in order to eliminate those of the previous ones In the work process.

Bei der Herstellung von Metalldrähten durch Auswalzen und Ausziehen von Barren bilden sich auf der Oberfläche Verunreinigungen in Form von Zunderüberzügen und Eisenteilchen. Beim weitemen Ausziehen des Drahtes bilden sich daraus splitterartige Teilchen, welche in der Oberfläche des Drahtes eingebettet sind, sich jedoch beim Biegen des Drahtes leicht loslösen können. Wird nun ein solcher Draht mit einer elektrischen Isoli? .rung versehen, so können beim Biegen die sich loslösenden Teilchen die Is;ollerung durchbrechen und Fehlerstellen verursachen. Wenn der Draht zu sehr kleinem Durchmesser ausgezogen wird, neigen .die Eisen:- und Zundersplitter dazu, im Draht zu verbleiben und können Drahtbruch während des 'Ziehvorganges verursachen. Es ist deshalb wichtig, die Eisen- und Zundersplitter von der Oberfläche der gewalzten Stangen zu entfernen, bevor diese zu Draht ausgezogen werden.In the manufacture of metal wires by rolling and drawing out of ingots, impurities in the form of scale coatings form on the surface and iron particles. When the wire is pulled out further, splinter-like forms form from it Particles which are embedded in the surface of the wire, however, are in the Bending of the wire can easily loosen. If such a wire is now connected to a electrical isoli? .rung provided, so when bending the detaching particles break the insulation and cause faults. When the wire is too much small diameter, the iron: - and flakes of scale tend to to remain in the wire and can cause wire breakage during the 'drawing process. It is therefore important to remove the iron and scale chips from the surface of the rolled Remove rods before pulling them out to wire.

Bisher wurde die Säuberung der Kupferoberfläche allgemein durch Beizen in Verbindung mit oxydierendem-Glühen bewirkt bzw. angestrebt. Diese rohe Arbeitsweise ist jedoch mit Werkstoffverlusten verbunden. Das bei der Oxydation gebildete Oxyd und das beim Belzen in. Lösung gegangene Kupfer bzw. Kupferoxyd sind verloren. Andererseits sind die bisher bekanntgewordenen mechanischen Einrichtungen zur Bearbeitung der Oberfläche der gewalzten Stangen ungeeignet, weil sie keine gleichmäßige und glatte Oberfläche ergeben. Sie werden deshalb auch nicht mehr angewendet. Es war ferner auch schwer, mit diesen Einrichtungen im ununterbrochen.-n. Arbeitsgang von Stangen bzw. Drähten einen gleichmäßigen Span abzunehmen.So far, cleaning of the copper surface has generally been done by pickling in connection with oxidizing annealing brought about or aimed at. This raw way of working however, it is associated with material losses. The oxide formed during oxidation and the copper or copper oxide which got into solution during the glaze are lost. on the other hand are the previously known mechanical ones Facilities for Machining of the surface of the rolled bars unsuitable because they are not uniform and smooth surface. They are therefore no longer used. It was also difficult to work with these facilities in an uninterrupted manner. Operation remove an even chip from bars or wires.

Ferner ist eine Vorrichtung bekanntgeword:en, bei der der Draht zunächst eine Schneiddüse und darauf -eine damit kombinierte Ziehdüse durchläuft. Demgegenüber ist die Vorrichtung gemäß der Erfindung so ausgebildet, daß der Draht zunächst eine Ziehdüse, darauf eine Führungsdüse und darauf die Schneiddüse durchläuft. Die Anordnung :einer Ziehdüse an erster Stelle bringt den Vorteil mit sich, daß der Draht zunächst einmal die gewünschte Form annimmt, so daß sich bei der Weiterverarbeitung eine gleichmäßige Sparabnahme ergibt. Die Führungsdüse in Kombination mit der Schneiddüse ermöglicht eine genauere Justierung des Drahtes und gewährleistet, daß die gesamte Oberfläche des Drahtes von der Schneiddüse :erfaßt wird. Die Vorrichtung gemäß der Erfindung :ergibt infolgedessen bei kontinuierlicher Arbeitsweise eine glatte Oberfläche der Walzstangen und gestattet ein sehr rasches Arbeiten.Furthermore, a device has become known in which the wire initially a cutting nozzle and then a drawing nozzle combined with it. In contrast the device according to the invention is designed so that the wire initially one Drawing nozzle, then a guide nozzle and then the cutting nozzle. The order : a drawing nozzle in the first place has the advantage that the wire first once takes on the desired shape, so that a uniform savings result. The guide nozzle in combination with the cutting nozzle allows a more precise adjustment of the wire and ensures that the entire Surface of the wire from the cutting nozzle: is detected. The device according to Invention: As a result, results in a smooth surface with continuous operation the rolling bars and allows very quick work.

Die Einrichtung gemäß der Erfindung ist in der Zeichnung beispielsweise dargestellt. Die Pfanne io ist auf einem geeigneten Gestell i i (in der Zeichnung nur teilweise dargestellt) gelagert und mit ihrem (einen Ende mittels des horizontalen Bolzens 12 an den Kopf 13 des vertikalen Tragblo.lzens I q. angelenkt. Das andere Ende der Pfanne stützt sich auf der Auflage 15, welche ein. Teil des Gestells i i ist. Der Bolzen 14 ist in einer Bohrung 16 im Teil 17 des Gestells i i gelagert und durch den Ring 19 und die Ringnut 18 in vertikaler Richtung fixiert. Die :eigentliche Bearbeitungsvorrichtung ist an der Pfanne io mittels der Tragplatte 20 und der Schrauben 21 festgeschraubt. Die Glättungseinrichtüng selbst besteht aus :einer Anzahl von Zieheisen und Führungsstücken, zwischen welchen ein Schneidstück angeordnet ist. Die Anordnung derselben ist in Fig. i dargestellt, und zwar im Axialschnitt. Die erste der Düsen ist mit 25 bezeichnet. Es ist dies jene Düse, welche der Draht zuerst passiert. Die Bohrung dieser Düse ist so bemessen, daß sie die Querschnittfläche des Drahtes um etwa io% vermindert. Die Düse 25 sitzt in dem Verstärkungslager 26, und dieses wiederum ist mittels der Klemme 28 im Träger 27 gelagert. Der Träger 27 ist schwenkbar mittels des Bolzens 29 an :der Drahtplatte 2o befestigt. Diese schwenkbare Anordnung ermöglicht es, die Düse 25 von dem Träger-3o der nächstfolgenden Düse hinwegzuklappen, so daß die nächstfolgende Düse aus dem Träger herausgenommen werden kann. Während des Betriebes ist der Träger 27 in der vertikalen Stellung durch den Träger 3o festgehalten.The device according to the invention is for example in the drawing shown. The pan io is on a suitable frame i i (in the drawing only partially shown) stored and with its (one end by means of the horizontal Bolt 12 to the head 13 of the vertical Tragblo.lzens I q. hinged. The other The end of the pan is supported by the support 15, which is a. Part of the frame i i is. The bolt 14 is mounted in a bore 16 in part 17 of the frame i i and fixed by the ring 19 and the annular groove 18 in the vertical direction. The: actual The processing device is on the pan by means of the support plate 20 and the screws 21 screwed tight. The smoothing device itself consists of: a number of Drawing dies and guide pieces, between which a cutting piece is arranged. The arrangement of the same is shown in Fig. I, in axial section. the the first of the nozzles is labeled 25. This is the nozzle that the wire will go first happened. The bore of this nozzle is dimensioned so that it has the cross-sectional area of the wire reduced by about 10%. The nozzle 25 sits in the reinforcement bearing 26, and this in turn is mounted in the carrier 27 by means of the clamp 28. The carrier 27 is pivotably attached to the wire plate 2o by means of the bolt 29. These pivotable arrangement allows the nozzle 25 to be removed from the carrier 3o of the next following Fold the nozzle away so that the next nozzle is removed from the carrier can be. During operation, the carrier 27 is in the vertical position held by the carrier 3o.

Die nächste Düse ist die Führungsdüse 31. Sie hat :die Aufgabe, den Draht der Schneiddüse zuzuführen. Der Durchmesser der Düse 31 ist um ein geringes kleiner als der des Drahtes, nachdem @er die Ziehdüse 25 verlassen hat. Diese :ergibt eine genügende Reibung, um den Draht fest zu fassen und ihn zu halten, wenn er die Schneiddüse passiert. Die Führungsdüse ist in der Versiärkungsbüchse 32 gelagert. Letztere steckt in dem Zwischenring 33 und ist durch den Schraubring 3,1 gehalten. Der Zwischenring 33 ist in einem verstellbaren Teil l35 durch die Klemmschraube 36 befestigt. Vermöge dieses verstellbaren Teils ist die Führungsdüse seitlich relativ zur Schneiddüse verschiebbar.The next nozzle is the guide nozzle 31. It has: the task, the Feed the wire to the cutting nozzle. The diameter of the nozzle 31 is small smaller than that of the wire after @it has left the drawing nozzle 25. This: results sufficient friction to grasp the wire firmly and hold it in place when the Cutting nozzle happens. The guide nozzle is mounted in the reinforcement sleeve 32. The latter is in the intermediate ring 33 and is held by the screw ring 3.1. The intermediate ring 33 is in an adjustable part l35 by the clamping screw 36 attached. By virtue of this adjustable part, the guide nozzle is laterally relative can be moved to the cutting nozzle.

In Fig.2 ist der Deutlichkeit halber der verstellbare Tei135 in Vorderansicht gezeichnet. Diese Figur zeigt deutlich, wie der verstellbare Teil35 durch die vier gleichmäßig verteilten justierschrau:ben 37 in dem Träger ;o befestigt ist. Der verstellbare Teil 35 ist ferner durch die Schrauben 38 und Muttern 39 mit seiner Hinterfläche an dein Träger 30 gedrückt.In FIG. 2, for the sake of clarity, the adjustable part is drawn in a front view. This figure clearly shows how the adjustable part 35 is fastened in the support by the four evenly distributed adjusting screws 37. The rear face of the adjustable part 35 is also pressed against the carrier 30 by the screws 38 and nuts 39.

Die nun folgende Schneiddüse ,1o ist mittels verschiedener Zwischenringe in dem Träger 4.1 befestigt. Der Abstand zwischen der Führungsdüse und den Schneiden der Schneiddüse ist so kurz wie möglich gemacht, so daß der verhältnismäßig weiche Draht sich während des Schneidevorganges nicht seitlich bewegen kann. Bei der beschriebenen Einrichtung ist dieser Abstand gerade so groß, daß dem abgearbeiteten Metall der Weg nach außen offen ist. Dem :entspricht etwa eine Distanz von 3 mm.The following cutting nozzle, 1o, is by means of various intermediate rings fastened in the carrier 4.1. The distance between the guide nozzle and the cutting edges the cutting nozzle is made as short as possible so that the relatively soft Wire cannot move sideways during the cutting process. With the described Facility, this distance is just so large that the processed metal The way to the outside is open. This: corresponds approximately to a distance of 3 mm.

Fig. 3 zeigt die Schneiddüse q.o, diese hat eine kegelige Bohrung und Leine kegelige Vorderfläche. Diese beiden bilden die Schneiden .42, 43. Der Kegel der inneren Bohrung hat eine Neigung von 3°, der Kegel der Außenfläche eine solche von 35°.Fig. 3 shows the cutting nozzle q.o, this has a conical bore and leash tapered front surface. These two form the cutting edges .42, 43. The The cone of the inner bore has an inclination of 3 °, the cone of the outer surface a those of 35 °.

Um den Abgang des durch die Schneiden i 42 der Schneiddüse q.o abgeschnittenen Metalls zu erleichtern, sind Hilfsschneiden 4.3' angebracht, welche das .abgenommene Metall in mehrere Späne aufteilen. Diese Hilfsschneiden sind in Fig. q. besonders dargestellt. Diese Hilfsschneiden sind dadurch entstanden, daß an der äußeren, kegeligen Fläche 4.2 der Düse .einige Flächen q.3 in gleicher Neigung angeschliffen worden sind. Die Länge dieser Hilfsschneiden ist größer als die Dicke des abgeschnittenen Metalls. Die angeschliffenen Flächen 43 sind sehr glatt poliert, so daß die Reibung des abgeschnittenen Metalls auf diesen Flächen sehr gering ist. Dies ist nötig, denn es wurde gefunden, daß die Oberfläche des bearbeiteten Drahtes rauh ausfällt, wenn die Reibung des abgearbeiteten Metalls auf den Flächen der Düse zu groß ist; bei sehr dünnen Drähten kann auch zu große Reibung Drahtbruch verursachen. ' Die fünfte Düse 5o ist eine Drahtziehdüse. Die Aufgabe dieser Düse besteht darin, die Oberfläche des Drahtes zu härten, nachdem er .die Schneiddüse verlassen hat. Sie kann auch dazu dienen, den Querschnitt des Drahtes um 10% zu vermindern. Die Reibung des Drahtes in der Ziehdüse bewirkt seine Spannung des Drahtes, so daß der Abschnitt desselben, welcher sich zwischen den beiden Ziehdüsen befindet, immer gestreckt bleibt. Es hat sich gezeigt, daß es empfehlenswert ist, die Abschnitte des Drahtes, welche sich nach und vor der Schneiddüse befinden, vollkommen gestreckt zu halten, so, daß das Metall, welches durch die Schneiddüse von dem Draht abgenommen wird, von gleichmäßiger Dicke ist. Die Ziehdüse 50 sitzt in der Buchse 5 i und diese wiederum in der Bohrung des Trägers 52, worin sie durch die Klemme 53 festgehalten wird. Der Träger 52 ist mit dem Träger 4i durch zwei Wände 49- verbunden, welche den gesamten Aufbau versteifen. und zwischen der Düse 4o und der Düse 50 einen. Behälter für Schmiermittel bilden. Ähnliche Behälter für S,chmiermitte154, 55 sind auch den Düsen 3 i und 25 vorausgesetzt.In order to facilitate the removal of the metal cut off by the cutting edges i 42 of the cutting nozzle qo, auxiliary cutting edges 4.3 'are attached, which divide the removed metal into several chips. These auxiliary cutting edges are shown in Fig. Q. specially shown. These auxiliary cutting edges are the result of the fact that on the outer, conical surface 4.2 of the nozzle, some surfaces q.3 have been ground at the same inclination. The length of these auxiliary cutting edges is greater than the thickness of the cut metal. The ground surfaces 43 are polished very smooth, so that the friction of the cut metal on these surfaces is very low. This is necessary because it has been found that the surface of the machined wire turns out to be rough if the friction of the machined metal on the surfaces of the nozzle is too great; In the case of very thin wires, excessive friction can also cause wire breakage. The fifth nozzle 50 is a wire drawing nozzle. The task of this nozzle is to harden the surface of the wire after it has left the cutting nozzle. It can also be used to reduce the cross-section of the wire by 10%. The friction of the wire in the drawing nozzle causes the wire to be tensioned, so that the section of the wire which is located between the two drawing nozzles always remains stretched. It has been found to be advisable to keep the portions of the wire which are after and in front of the cutting nozzle perfectly stretched so that the metal which is removed from the wire by the cutting nozzle is of uniform thickness. The drawing nozzle 50 is seated in the socket 5 i and this in turn in the bore of the carrier 52, in which it is held by the clamp 53. The beam 52 is connected to the beam 4i by two walls 49- which stiffen the entire structure. and between the nozzle 4o and the nozzle 50 one. Form containers for lubricants. Similar containers for lubricants 154, 55 are also required for nozzles 3 i and 25.

Die beschriebene Vorrichtung kann in Verbindung finit einer gebräuchlichen Drahtziehbank benutzt werden. Sie wird dann zwischen zwei Trommeln @derselben eingeechaltet. Bei der Bearbeitung von Kupfer soll die Geschwindigkeit, finit der der Draht die Maschine durchläuft, etwa 6o Im in der Minute betragen.The device described can be used in conjunction with a finite one Wire drawing bench can be used. She is then engaged between two drums @the same. When processing copper, the speed should be the finite of the wire Machine runs through at about 6o Im per minute.
